The reason the original code is setting sev->fh to NULL is to signal to users of the event framework that the unsubscription has happened, but since their is no shared lock between the event framework and users of it, this is inherently racy, and it also turns out to be unnecessary as long as both the event framework and the user of the framework do their own locking properly and the user guarantees that it holds no references to the subcribed_event structure after its del operation has been called. This is best explained by looking at the only code currently checking for sev->fh being set to NULL on unsubscribe, which is the v4l2-ctrls.c send_event function. Here is the relevant code from v4l2-ctrls: send_event(): if (sev->fh && (sev->fh != fh || (sev->flags & V4L2_EVENT_SUB_FL_ALLOW_FEEDBACK))) v4l2_event_queue_fh(sev->fh, &ev); Now lets say that v4l2_event_unsubscribe and v4l2-ctrls: send_event() race on the same sev, then the following could happens: 1) send_event checks sev->fh, finds it is not NULL <thread switch> 2) v4l2_event_unsubscribe sets sev->fh NULL 3) v4l2_event_unsubscribe calls v4l2_ctrls del_event function, this blocks as the thread calling send_event holds the ctrl_lock <thread switch> 4) send_event calls v4l2_event_queue_fh(sev->fh, &ev) which not is equivalent to calling: v4l2_event_queue_fh(NULL, &ev) 5) oops, NULL pointer deref. Now again without setting sev->fh to NULL in v4l2_event_unsubscribe and without the (now senseless since always true) sev->fh != NULL check in 1) send_event is about to call v4l2_event_queue_fh(sev->fh, &ev) <thread switch> 2) v4l2_event_unsubscribe removes sev->list from the fh->subscribed list <thread switch> 3) send_event calls v4l2_event_queue_fh(sev->fh, &ev) 4) v4l2_event_queue_fh blocks on the fh_lock spinlock <thread switch> 5) v4l2_event_unsubscribe unlocks the fh_lock spinlock 6) v4l2_event_unsubscribe calls v4l2_ctrls del_event function, this blocks as the thread calling send_event holds the ctrl_lock <thread switch> 8) v4l2_event_queue_fh takes the fh_lock 7) v4l2_event_queue_fh calls v4l2_event_subscribed, does not find it since sev->list has been removed from fh->subscribed already -> does nothing 9) v4l2_event_queue_fh releases the fh_lock 10) the caller of send_event releases the ctrl lock (mutex) <thread switch> 11) v4l2_ctrls del_event takes the ctrl lock 12) v4l2_ctrls del_event removes sev->node from the ev_subs list 13) v4l2_ctrls del_event releases the ctrl lock 14) v4l2_event_unsubscribe frees the sev, to which no references are being held anymore Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
| * | | | | | | | | | [media] v4l2-event: Remove pending events from fh event queue when unsubscribingHans de Goede2011-11-08

We used 1960 as the offset to make leap year consistent, but for a device's first use, its YEAR register is 0 and the system year will be parsed as 1960 which is not a valid UNIX time and will cause many applications to fail mysteriously. So we use 1972 instead to fix this issue. Updated patch which adds a sanity check suggested by Mathias This isn't a change in behaviour for systems, because 1972 is the one we actually use. It's the old version in upstream which is out of sync with all devices.
